GIVEN
Four expressions in terms of x and y where
[tex]\begin{gathered} x=6 \\ y=5 \end{gathered}[/tex]
SOLUTION
Expression 1:
[tex]12+x[/tex]
Substitute x = 6 into the expression:
[tex]12+x=12+6=18[/tex]
Expression 2:
[tex]3x+y[/tex]
Substitute for x and y into the expression:
[tex]3(6)+5=18+5=23[/tex]
Follow the same pattern for the other two expressions:
[tex]\begin{gathered} 4y-10=4(5)-10=20-10=10 \\ \frac{1}{2}xy=\frac{1}{2}\cdot6\cdot5=\frac{30}{2}=15 \end{gathered}[/tex]
ANSWER
[tex]\begin{gathered} 12+x=18 \\ 3x+y=23 \\ 4y-10=10 \\ \frac{1}{2}xy=15 \end{gathered}[/tex]
